Detectives investigating Wednesday's attack are looking into a similar incident in Peckham, south-east London, earlier this month. In both cases the two suspects are described as one black and one Asian.
Meanwhile, the victim of the Regent's Park attack returned to the scene of the crime with detectives yesterday in an effort to uncover new clues.
The woman was also interviewed at length by specially trained officers attempting to trace the two attackers who led her at knife-point from Great Portland Street station to Regent's Park across a busy six-lane road during the rush hour.
More calls were received from people who believe they may have seen the attack on Wednesday.Reuse content
